Alberta Stroke Programme Early CT Score (ASPECTS)

ASPECTS is a quantitative topographic prognostic score based on unenhanced CT scan in patients with middle cerebral artery infarction. For each from 10 segments, one point is deducted from initial 10 points for each segment with detectable ischemic changes. A score ≤7 points predicts worse functional outcome at 3 months and an increased risk of symptomatic intracranial hemorrhage.
